Pros
Tons of autonomy and room to innovate. Large company w/ big scale to learn about new technology challenges. New technologies are embraced if started in smaller areas to learn in first then scale. Failure is encouraged as long as it is followed by learning which can really accelerate personal growth. Flexible work schedule coupled with interesting impactful work. Awesome teammates that want everyone succeed. Politics are not allowed. Relatively flat org structure where title is less important in discussions. Best ideas always win not the high paid person.
Cons
Depends on your viewpoint. Some folks would see things I see as pros as cons. For example, the work here isn't handed to you in a bulleted list. We are expected to understand the business problem and come up with a viable solution. I enjoy that creative flexibility and responsibility it puts on me. Some folks might not. Not all of our work falls into that bucket but the successful folks find a way to make it happen and it's the most rewarding part of the job to me.
